When does the blue rain sprout?
As a relatively fast and vigorous awake climbing plant you have to worry about the sprouting of your Blauregens actually hardly. He is considered hardy and robust. Even after a radical cut, he can recover quite well.
The sprouting of the leaves
In May, the blue rain drops its new leaves. They are usually quite bright. Sometimes it gives the impression that the leaves turn yellow due to chlorosis, but in most cases there is no cause for concern. Over time, the leaves darken. Only if this does not happen you should search for the cause of the disease.
The budding of the flowers
The flowers of a Blauregens show up depending on the weather and climate in April or May. Then the flowering time lasts into the summer. Often, at the end of the summer, there is a after-flowering that is not as impressive as the first one. By a slight pruning you can promote the budding buds. However, a blue rain needs a few years until it starts to bloom at all.
Is a frozen blue rain going on again?
The aboveground parts of the wisteria, especially young shoots and / or buds, may freeze over a prolonged period of frost. As a rule, however, the blue rain sprouts easily in the spring. It looks different, however, when the roots freeze. But this happens only rarely, at best when planting in a vessel.
For this reason, a wisteria in the bucket needs a special winter protection, so that the frost can not reach the roots. Either hibernate the plant in a cold greenhouse, in the garage or a cool basement room or wrap the bucket with an old blanket, jute sacks or fleece. Also, consider protecting the bottom by wrapping or using a polystyrene board.
